Xylem VFD Quick Start Safety Guidelines - Manual (Page 2)

Always treat this
controller as energized
until power supply to the controller
has been removed for 5 minutes.
Electrocution Hazard.
Opening SWITCH INPUT
does not de-energize controller or
any of it’s outputs.
Avoid property
damage caused by
pressure relief valve opening. Pipe
the pressure relief valve discharge
to a drain or other location so that
property damage and flooding will
not occur.
Locate the tank and
transducer where they
will not freeze.
Do not install any
valves, flow control
devices or filters between the
pressure transducer and the pump.
It is allowable to run branches
off the pipe between the pump
and transducer as long as no flow
restricting devices are between the
pump and transducer.
Any exposed metal
in the system piping,
including transducer case, must be
grounded to the service entrance per
NFPA 70: National Electrical Code,
Article 250.
DANGER
CAUTION
WARNING
Motor Overload Setting Dial
Failure to properly
adjust the Motor
Overload Setting before applying
power may damage the motor or wire
and void the warranty.
Pressure Adjustment
The INCREASE and DECREASE
pushbuttons are used to set the
desired pressure. To adjust pressure,
press and hold (do not tap) the button
until the desired pressure is obtained.
It may take a full minute to adjust the
pressure from maximum to minimum,
please be patient. Pressure can only
be changed when the pump-motor is
running.
Controller Status Indicator (Light
Visible Through Window in Cover)
The controller status indicator light
has 3 possible modes:
• Solid green = Standby, pump not
running. There is no water flow or
the SWITCH INPUT is open.
• Blinking green = Pump running.
There is flow (possibly a leak) and
the SWITCH INPUT terminals are
connected to each other (closed).
• Red = Error/Fault. Light will blink
to indicate a particular fault. See
Troubleshooting Section for Fault
Codes.
Splicing Drop Cable
The underwater connection where
the drop cable connects to the
motor wires must be done using a
waterproof heat shrink kit.
